zooming in on image, showing more details

I am working on a little project and want to implement some sort of "google maps" zooming. What I mean with that is that I want to show an image, and let the user be able to zoom in into a bit of the picture.

The first image should show an overall view of an airport, with its terminals and gates ect. But when zooming in on a terminal it should show more details on where bus stops, taxi stops, info, café's ect are located. It should NOT be a map.

I have searched Google a bit, but couldn't really find anything. Anyone who has any suggestions? Preferable links to tutorials for similar things?

Best regards,
Paul Peelen

The standard way to implement this is by using a UIScrollView and within the UIScrollView add a custom UIView with CATiledLayer layers. You will render the image by drawing (setting content) to the inner CATiledLayer layers. Look at the PhotoScroller sample project.
